difference between string and list

[lincoln rutledge]

I'm having trouble figuring out the difference between a string and a
list.

I know that:
string = "foo bar"

is a list of characters, "foo bar", and string[0] is "f".

while:

list = ["foo", "bar"]
and list[0] is "foo".

strings have methods like string.count("f") returns 1. What methods do
lists have? Is it a similar class to string?

thanks,
Lincoln

Strings and lists are similar but not the same. dir(string) will show
you the methods available for strings. dir(list) will show you the
methods available for lists. See also the "built-in types" section
of the Python Library Reference Manual, the section on sequence types.

['R', 'e', 'a', 'l', 'l', 'y', ' ', '?', ' ', 'S', 'e', 'e', 'm', 's', '
', 'q', 'u', 'i', 't', 'e', ' ', 'o', 'b', 'v', 'i', 'o', 'u', 's', ' ',
't', 'o', ' ', 'm', 'e', '.']

No. It's a string. Python doesn't have a "character" type.

, "foo bar", and string[0] is "f".

Yes. And ?

while:

list = ["foo", "bar"]
and list[0] is "foo".

So ?

strings have methods like string.count("f") returns 1. What methods do
lists have?

Open your interactive Python interpreter and type

Is it a similar class to string?

Not exactly. Both are sequences, that's all. FWIW, try this:

"foo"[0] = "b"
